Answer:
Formula for Central Angle: θ = Arc Length×180°π×r
Central Angle Formula: s=r×θ
Double Angle Formula: (Has three) cos2θ= cos2θ−sin2θ sin2θ=2sinθcosθ tan2θ=2tanθ/1−2 tan2θ
Step-by-step explanation:
Answer:
The truck travel must to have a constant speed of
Step-by-step explanation:
we have
where
d expresses a car's distance in feet
t is the number of seconds
<em>Find the distance d for t=8 sec</em>
<em>Find the distance d for t=8.2 sec</em>
The total distance in this interval of 0.2 sec is
<em>Find the speed of the car</em>
Divide the total distance by the time
therefore
The truck travel must to have a constant speed of
Answer:
23/25 when reduced to the simplest form.
Step-by-step explanation:
write down the number as a fraction of one
0.92 = 0.92/1
so we multiply both numerator and denominator by 100
Then 0.92/1 = ( 0.92x100) / ( 1x100)
= 92/100
Now reduce the numerator and denominator by GCD between in this case
GCD ( 92,100) = 4
so, 92/ 4
100/ 4
=23/25
